On-chip magnetic cooling of a nanoelectronic device [PDF]
Scientific Reports, 2017 AbstractWe demonstrate significant cooling of electrons in a nanostructure below 10 mK by demagnetisation of thin-film copper on a silicon chip. Our approach overcomes the typical bottleneck of weak electron-phonon scattering by coupling the electrons directly to a bath of refrigerated nuclei, rather than cooling via phonons in the host lattice ...

Nanoelectronic thermometers optimised for sub-10 millikelvin operation [PDF]
, 2015 We report the cooling of electrons in nanoelectronic Coulomb blockade thermometers below 4 mK. Above 7 mK the devices are in good thermal contact with the environment, well isolated from electrical noise, and not susceptible to self-heating.

Materials and Devices for On-Chip and Off-Chip Peltier Cooling: A Review [PDF]
IEEE Transactions on Components, Packaging and Manufacturing Technology, 2021 The thermoelectric effect forms the basis of Peltier cooling that has attracted interest for solid-state refrigeration for more than a century. The dearth of materials level efficiency in converting between heat and electricity has limited widespread applications.
